The Rohm BD6107 driver can pass a fixed GPIO line using the old
GPIO API using platform data. As there are no in-tree users of this
platform data since 2013, we can convert this to use a GPIO descriptor
and require any out-of-tree consumers to pass the GPIO using
a machine descriptor table instead.

There are a lot of similar global registers being used across multiple SoCs
from Unisoc. But most of these registers are assigned with different offset
for different SoCs. It is hard to handle all of them in an all-in-one
kernel image.
Add a helper function to get regmap with arguments where we could put some
extra information such as the offset value.

Few ROHM PMICs allow setting the voltage states for different system states
like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific
mechanisms. bd718x7 driver implemented device-tree parsing functions for
these state specific voltages. The parsing functions can be re-used by
other ROHM chip drivers like bd71828. Split the generic functions from
bd718x7-regulator.c to rohm-regulator.c and export them for other modules
to use.

Thanks to Stephen Boyd I today learned we can use platform_device_id
to do device and module matching for MFD sub-devices!
Do device matching using the platform_device_id instead of using
explicit module_aliases to load modules and custom parent-data field
to do module loading and sub-device matching.

Add util_pre_suspend() and util_pre_resume() for some hv_utils devices
(e.g. kvp/vss/fcopy), because they need special handling before
util_suspend() calls vmbus_close().
For kvp, all the possible pending work items should be cancelled.
For vss and fcopy, some extra clean-up needs to be done, i.e. fake a
THAW message for hv_vss_daemon and fake a CANCEL_FCOPY message for
hv_fcopy_daemon, otherwise when the VM resums back, the daemons
can end up in an inconsistent state (i.e. the file systems are
frozen but will never be thawed; the file transmitted via fcopy
may not be complete). Note: there is an extra patch for the daemons:
"Tools: hv: Reopen the devices if read() or write() returns errors",
because the hv_utils driver can not guarantee the whole transaction
finishes completely once util_suspend() starts to run (at this time,
all the userspace processes are frozen).
util_probe() disables channel->callback_event to avoid the race with
the channel callback.

When a Linux hv_sock app tries to connect to a Service GUID on which no
host app is listening, a recent host (RS3+) sends a
CHANNELMSG_TL_CONNECT_RESULT (23) message to Linux and this triggers such
a warning:
unknown msgtype=23
WARNING: CPU: 2 PID: 0 at drivers/hv/vmbus_drv.c:1031 vmbus_on_msg_dpc
Actually Linux can safely ignore the message because the Linux app's
connect() will time out in 2 seconds: see VSOCK_DEFAULT_CONNECT_TIMEOUT
and vsock_stream_connect(). We don't bother to make use of the message
because: 1) it's only supported on recent hosts; 2) a non-trivial effort
is required to use the message in Linux, but the benefit is small.
So, let's not see the warning by silently ignoring the message.

The Rohm BD2802 have no in-kernel users so we can drop the
GPIO number from the platform data and require users to
provide the GPIO line using machine descriptors.
As the descriptors come with inherent polarity inversion
semantics, we invert the calls to set the GPIO line such
that 0 means "unasserted" and 1 means "asserted".
Put a note in the driver that machine descriptor tables
will need to specify that the line is active low.

Commit bc081dd6e9f6 ("kbuild: generate modules.builtin") added
infrastructure to generate modules.builtin, the list of all
builtin modules.
Basically, it works like this:
- Kconfig generates include/config/tristate.conf, the list of
tristate CONFIG options with a value in a capital letter.
- scripts/Makefile.modbuiltin makes Kbuild descend into
directories to collect the information of builtin modules.
I am not a big fan of it because Kbuild ends up with traversing
the source tree twice.
I am not sure how perfectly it should work, but this approach cannot
avoid false positives; even if the relevant CONFIG option is tristate,
some Makefiles forces obj-m to obj-y.
Some examples are:
arch/powerpc/platforms/powermac/Makefile:
obj-$(CONFIG_NVRAM:m=y) += nvram.o
net/ipv6/Makefile:
obj-$(subst m,y,$(CONFIG_IPV6)) += inet6_hashtables.o
net/netlabel/Makefile:
obj-$(subst m,y,$(CONFIG_IPV6)) += netlabel_calipso.o
Nobody has complained about (or noticed) it, so it is probably fine to
have false positives in modules.builtin.
This commit simplifies the implementation. Let's exploit the fact
that every module has MODULE_LICENSE(). (modpost shows a warning if
MODULE_LICENSE is missing. If so, 0-day bot would already have blocked
such a module.)
I added MODULE_FILE to <linux/module.h>. When the code is being compiled
as builtin, it will be filled with the file path of the module, and
collected into modules.builtin.info. Then, scripts/link-vmlinux.sh
extracts the list of builtin modules out of it.
This new approach fixes the false-positives above, but adds another
type of false-positives; non-modular code may have MODULE_LICENSE()
by mistake. This is not a big deal, it is just the code is always
orphan. We can clean it up if we like. You can see cleanup examples by:
$ git log --grep='make.* explicitly non-modular'
To sum up, this commits deletes lots of code, but still produces almost
equivalent results. Please note it does not increase the vmlinux size at
all. As you can see in include/asm-generic/vmlinux.lds.h, the .modinfo
section is discarded in the link stage.

The arm64 version of archrandom.h will need to be able to test for
support and read the random number without preemption, so a separate
query predicate is not practical.
Since this part of the generic interface is unused, remove it.

The separate blocking pool is going away. Start by ignoring
GRND_RANDOM in getentropy(2).
This should not materially break any API. Any code that worked
without this change should work at least as well with this change.

PCIe controller is based of Synopsys DesignWare PCIe core.
Intel PCIe driver requires Upconfigure support, Fast Training
Sequence and link speed configurations. So adding the respective
helper functions in the PCIe DesignWare framework.
It also programs hardware autonomous speed during speed
configuration so defining it in pci_regs.h.
Also, mark Intel PCIe driver depends on MSI IRQ Domain
as Synopsys DesignWare framework depends on the
PCI_MSI_IRQ_DOMAIN.

Gen4 hardware provides new MRPC commands to read and write directly from
any address in the PCI BAR (which Microsemi refers to as GAS). Since
accessing BARs can be dangerous and break the driver, we don't want
unprivileged users to have this ability.
Therefore, require CAP_SYS_ADMIN for the local and remote GAS access MRPC
commands. Privileged processes will already have access to the BAR through
the sysfs resource file so this doesn't give userspace any capabilities it
didn't already have.

Remove several functions that are no longer used now that the
conversion of cec drivers to cec_notifier_conn_(un)register() and
cec_notifier_cec_adap_(un)register() is complete.

boundary->width and boundary->height are sizes relative to
boundary->left and boundary->top coordinates, but they were not being
taken into consideration to adjust r->left and r->top, leading to the
following error:
Consider the follow as initial values for boundary and r:
struct v4l2_rect boundary = {
.left = 100,
.top = 100,
.width = 800,
.height = 600,
}
struct v4l2_rect r = {
.left = 0,
.top = 0,
.width = 1920,
.height = 960,
}
calling v4l2_rect_map_inside(&r, &boundary) was modifying r to:
r = {
.left = 0,
.top = 0,
.width = 800,
.height = 600,
}
Which is wrongly outside the boundary rectangle, because:
v4l2_rect_set_max_size(r, boundary); // r->width = 800, r->height = 600
...
if (r->left + r->width > boundary->width) // true
r->left = boundary->width - r->width; // r->left = 800 - 800
if (r->top + r->height > boundary->height) // true
r->top = boundary->height - r->height; // r->height = 600 - 600
Fix this by considering top/left coordinates from boundary.

DVB-T2. Only terrestrial reception was tested on Polish and Czech
multiplexes.

The v4l2_buffer structure contains a 'struct timeval' member that is
defined by the user space C library, creating an ABI incompatibility
when that gets updated to a 64-bit time_t.
As in v4l2_event, handle this with a special case in video_put_user()
and video_get_user() to replace the memcpy there.
Since the structure also contains a pointer, there are now two
native versions (on 32-bit systems) as well as two compat versions
(on 64-bit systems), which unfortunately complicates the compat
handler quite a bit.
Duplicating the existing handlers for the new types is a safe
conversion for now, but unfortunately this may turn into a
maintenance burden later. A larger-scale rework of the
compat code might be a better alternative, but is out of scope
of the y2038 work.
Sparc64 needs a special case because of their special suseconds_t
definition.
